Active decoupling system for explosion protection assembly at bottom of vehicle

Abstract

The invention relates to an active decoupling system for an explosion protection assembly at the bottom of a vehicle. Comprising a bottom explosion event detection device, a decoupling trigger device, a decoupling action device and a guide connection device, and the bottom explosion event detection device is located on a vehicle bottom protection assembly and composed of a plurality of parallel distributed stress wave or electromagnetic wave detectors; after receiving the explosion event signal, the decoupling trigger device performs corresponding processing and outputs a decoupling action signal; the decoupling action device performs decoupling action after receiving the decoupling action signal; the guide connecting device comprises guide elements and limiting elements, each guide element is composed of an embedded thin rod and a thick pipe, and the limiting elements are located on the outer side of the thin rod and the inner wall of the thick pipe. The explosion event detection device is used for detecting the explosion event at the bottom of the vehicle, decoupling separation of the protection assembly and the vehicle bottom deck is achieved through the decoupling device, after the vehicle is subjected to explosion impact, explosion impact damage is reduced through the decoupling action of the protection assembly, and the vehicle passenger protection capacity is improved.

Description

technical field [0001] The invention belongs to the field of vehicle protection, and in particular relates to an active decoupling system for explosion protection components at the bottom of a vehicle. Background technique [0002] At present, the main threat that military vehicles face on the asymmetric combat battlefield is explosives at the bottom of vehicles such as IEDs. The explosion of explosives instantly generates an overpressure shock wave that acts on the bottom deck of the vehicle, causing rapid deformation of the bottom deck and transmitting extremely high acceleration shocks to the vehicle. occupants, causing injury or even death to the occupants. [0003] Aiming at the threat brought by the bottom explosion, most countries in the world currently adopt the method of adding bottom protection components to improve the occupant protection ability of armored vehicles in the impact of bottom explosions. At present, the main forms of bottom protection components are ...

Problems solved by technology

[0004] However, subject to factors such as payload, maneuverability, and passing performance, the weight of the bottom protection component cannot be increased without limit, resulting in the armored vehicle's protection capability can only be improved within a limited range
